Waitsia-3 well verifies gas field extension

AWE Limited, the operator of the Waitsia gas project in Western Australia production license L1/L2 has confirmed the extension of the gas field. 

The preliminary analysis of wireline log and pressure data from the Waitsia-3 appraisal well has confirmed the southern extension of the Waitsia gas field by encountering strong gas shows across a 150 m gross interval including the Kingia and High Cliff Sandstone reservoir targets.

The well was successfully drilled to a Total Depth of 3,612 m into crystalline basement, having drilled through all primary and secondary targets.

Strong gas shows were encountered in the Kingia and High Cliff Sandstone intervals as well as minor shows in the Irwin River Coal Measures.

Preliminary interpretation of the Kingia reservoir shows excellent conventional reservoir qualities, among the best observed in the field to date, and considerably better than pre-drill estimates, AWE said.

The gross Kingia reservoir interval of 52 m contains 20 m of net gas pay with reservoir quality exceeding that intersected in Waitsia-1 and Waitsia-2. The Kingia net reservoir interval in Waitsia-3 is approximately double that observed in other wells in the field and confirms the laterally extensive nature of this reservoir.

David Biggs, CEO and managing director of AWE, said, the company will continue the analysis and evaluation of the Waitsia-3 data, but the company is already looking ahead to the Waitsia-4 appraisal well which is expected to spud in the first half of July.

AWE operates the production license L1/L2 in the northern Perth Basin, Western Australia with a 50 percent stake while Origin Energy holds the remaining 50 percent.
